8.4.7
Host 1 Device Address Register 0xC088
Host 2 Device Address Register 0xC0A8
Host n Device Address Register [W]
Figure 8-22. Host n Device Address Register
Register Description
The Host n Device Address register is a write-only register that contains the USB Device Address that the host wishes to
communicate with.
Address
(Bits [6:0])
The Address field contains the value of the USB address for the next device that the host is going to communicate with. This
value needs to be written by firmware.
Reserved
All reserved bits must be written as ‘0’.
8.4.8
Host 1 Interrupt Enable Register 0xC08C
Host 2 Interrupt Enable Register 0xC0AC
Host n Interrupt Enable Register [R/W]
Figure 8-23. Host n Interrupt Enable Register
Register Description
The Host n Interrupt Enable register will allow control over host-related interrupts.
In this register a bit set to ‘1’ enables the corresponding interrupt while ‘0’ disables the interrupt.
VBUS Interrupt Enable
(Bit 15)
The VBUS Interrupt Enable bit enables or disables the OTG VBUS interrupt. When enabled this interrupt triggers on both rising
and falling edge of VBUS at the 4.4V status (only supported in Port 1A). This bit is only available for Host 1 and is a reserved bit
in Host 2.
1:
Enable VBUS interrupt
0:
Disable VBUS interrupt
